Anyone know how to unseize a piston and how do I push the working piston back in so I can get the brake pads back in. At least before this the front brake still slowed the scoot down...not anymore.....
It's just one setback after another with this scooter, my head is down right now.

I've got a shopping list for scooter rally in Aberfoyle tomorrow, I'm hoping a new caliper isn't going to be an addition to the list.. FFS
